Fire/flames moving and effects

Hey everybody i am new to tech art and VFX, for a game at our school we are working on i made these flames:



However i ran into an issue applying this effect to the plane which it had to be attached to.
the fire should envelop the plane and the smoke should continue from this while the plane goes down or explodes…leaving a massive smoke trail.
yet when applied the flames and smoke seem barely envelope the plane and just seem to spawn random after the plane and not being really enveloped and smoke seems to spawn in the same less density further away from the plane.
how can i fix this or adjust it to make it dense and enveloping the plane?

this is what happens.
and this is what i want it to make it look like:
